Hello Everyone, I'm seeing a very strange error in Google Webmaster tools since few days. Google is showing me "406 error", I've checked with hosting guys and according to them, everything is fine. But these errors are increasing. Before sometime, it was 4 and now, they're 16. Here's the type of error, can anyone help me to sort this out. http://domain.com/?option=com_googl...../../../../../../../../../proc/self/environ
Usually an issue with your server not sending back the correct headers, or a weird and wonderful browser being used. 406 is usually generated because 'accept headers' aren't being used. It might be someone trying to view your site in a broken browser, although if it's in Webmaster tools then that sounds like Googlebot has been struggling to crawl the pages. Your link is broken (goes to domain.com) so it's a little difficult to tell much more. I can see that it's trying to visit ../../../../../../../../proc/self/environ - this looks like it might be an automated script scanning your site for security holes. Make sure everything is locked down correctly (SQL queries escaped an sanitized first and foremost).
